Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to
The present invention relates to a jig serving as a simulated bait for inviting a fish by applying a vertical force by pulling or loosening a fishing line and moving it by a difference in receiving water pressure.

[0002]

2. Description of the Related Art Conventionally, a jig shown in FIG. 14 is known as this kind. In this jig, a jig body 1 has an elongated and flat shape, and a fishing line locking portion 3 for locking a fishing line 2 is provided at one longitudinal end thereof, and a fishing hook 4 is provided at the other end. Underwater, the jig body 1 is supported in a vertical state with the hook 4 down (the state shown in FIG. 14). In this state, when the fishing line 2 is pulled or loosened to apply a vertical movement to the jig, the jig body 1 becomes flat. Makes a vertical trajectory while swaying in small increments due to the difference in water pressure received on the left and right surfaces (Fig. 1
5).

[0003] Since the above jig is a vertical movement, it can produce only a very unnatural movement of the fish to be simulated, and it can only appeal to a swimming layer of a fish called a shelf or a fish arriving at the bottom for a short time. There was such a problem.

FIG. 16 shows a jig for solving such a problem.
There is what was shown in. This jig is configured such that an elongated jig body 1 is supported in a horizontally long direction and is used.
Is provided. At the rear end of the jig body 1, a water receiving plate 5 having an upper surface and a lower surface as water receiving surfaces is provided. The jig thus configured is supported in a substantially horizontal state underwater (the state shown in FIG. 16), and when the fishing line 2 is pulled upward from this state, water pressure is applied to the upper surface of the jig body 1 and the fishing line engaging portion 3
Due to the difference between the water receiving area on the front upper surface and the water receiving area on the rear upper surface, the front side rises and tilts, and when further raised,
The force applied to the upper surface of the water receiving plate 5 by the water pressure acts as a force for pushing the water receiving plate 5 forward, the jig moves forward while rising, and when the fishing line 2 is loosened, the water pressure is applied to the lower surface of the water receiving plate 5. Is added, and the front side faces downward and descends.

[0005]

According to the jig shown in FIG. 16, the movement in the forward direction is added to the movement in the vertical direction, and is closer to the movement of the fish to be simulated than the jig shown in FIG. However, when the jig body 1 is lifted,
The water receiving plate 5 is provided at the rear end of the jig body 1, and the water pressure applied to the rear end of the jig body 1 by this water pressure acts on the rear end of the jig body 1. The force in the direction is converted to a rotational moment (Fig. 1
7) The forward movement efficiency is low, and the same is true when descending. The locus of the movement is short in the forward movement distance as shown in FIG. 18, and the movement of the fish to be simulated is not satisfactory. is there.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a jig capable of efficiently converting a vertical movement into a forward movement so as to be closer to the movement of a fish to be simulated.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a jig body having a fishing line engaging portion on an upper surface and a fishing hook on a lower surface. The cross-sectional shape in the direction is formed so that the width at least other than the rear end portion is wider than the vertical width, the entire upper surface is an upper water receiving surface, the entire lower surface is a lower water receiving surface, and the entire upper surface of the jig body is In the formed upper water receiving surface, the area behind the fishing line engaging portion is larger than the area on the front side, and the front part of the jig body is heavier than the rear part.

[0008] With this structure, the upper water receiving surface of the jig body has a larger area on the rear side than on the front side of the fishing line locking portion. When the side rises and inclines, when it is further raised, the force applied to the upper water receiving surface by water pressure acts as a force to push the jig body forward, and the jig body moves forward while rising, but at this time, the upper water receiving surface of the jig body Although the rear side has a larger area, the water pressure from above is applied to the upper water receiving surface of the entire upper surface of the jig main body, so the force in the forward direction exerted by the water pressure is slightly converted to a rotational moment, together,
Since the front part of the jig body is made heavier than the rear part, a weight moment acts on the front part side of the jig body due to the weight difference between the front part and the rear part, whereby the force in the forward direction is converted into a rotational moment. The jig body moves forward efficiently and a long distance forward movement is obtained,
Then, when the fishing line is loosened, the front part is heavy, so the front part descends downward, but at this time, water pressure from below is applied to the lower water receiving surface of the jig body, and the force of this water pressure pushes the jig body forward. As a force, the jig body moves forward while descending, and a long forward movement can be obtained as in the case of the above-mentioned ascent.

According to a second aspect of the present invention, the jig body of the first aspect has a cross-sectional shape in a lateral direction which is a substantially isosceles triangle in which an upper water receiving surface is formed by two oblique sides.

[0010] With this configuration, when the fishing line is pulled upward in the water, the force applied to the upper water receiving surface by the water pressure is equally applied to the two slopes constituting the upper water receiving surface, and pressed by an equal force. As a result, the jig body is prevented from skidding when ascending, and can be moved substantially linearly.

According to a third aspect of the present invention, the jig body of the first aspect has an elliptical cross-sectional shape in the lateral direction.

With this configuration, when the fishing line is pulled upward in the water, the force applied to the upper water receiving surface by the water pressure is uniformly applied to the arcuate surfaces on both sides constituting the upper water receiving surface, and pressed against each other by an equal force. As a result, the jig body is prevented from skidding when ascending, and can move forward almost linearly.Also, when descending, similarly to when ascending, the force due to water pressure is applied to the arc surfaces on both sides constituting the lower water receiving surface. Since the jig body is evenly applied and pressed with an equal force, even when the jig body is lowered, the jig body can be prevented from slipping and the jig body can be advanced substantially linearly.

According to a fourth aspect of the present invention, a ridge extending in the front-rear direction is formed at the center of the upper water receiving surface of the jig body according to the first aspect.

[0014] With this configuration, when the jig body is raised, the ridge formed at the center of the upper water receiving surface of the jig body prevents the jig body from skidding, and the jig body can be advanced substantially linearly.

[0015] The invention according to claim 5 is the invention according to claims 1, 2, and 3.
The jig body according to the third or fourth aspect is characterized in that the upper surface of the jig main body is formed with a mountain-shaped inclined surface that is inclined forward and backward with the portion where the fishing line engaging portion is provided as a top.

With this configuration, the upper water receiving surface of the jig main body has a larger area on the rear side than on the front side of the fishing line locking portion. Therefore, when the fishing line is pulled upward in water, the front water receiving surface becomes larger due to the difference in the water receiving area. The side rises and inclines, but at this time, since the upper water receiving surface of the jig body is formed with a mountain-like inclined surface that inclines back and forth with the portion where the fishing line locking portion is provided as the apex,
In the state where the jig body is inclined, the water receiving surface on the front side of the fishing line engaging portion exhibits an angle close to horizontal, while the water receiving surface on the rear side is greatly inclined.

As a result, when the fishing line is pulled up, a force in the forward direction acts on the jig body due to the water pressure applied to the rear water receiving surface, and at the same time, the force in the forward direction is converted into a rotational moment. However, the force of the water pressure applied to the water receiving surface on the front side suppresses the force for converting the force in the forward direction into a rotational moment, so that the jig body efficiently advances, and the jig body advances for a longer distance. Movement is obtained.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a jig according to the present invention will be described in detail with reference to the drawings. 1 to 4 show an example of an embodiment of a jig head according to the present invention. In this example, the jig main body 1 has a horizontally long shape, a fishing line locking portion 3 is provided on an upper surface thereof, and a fishing hook 4 is provided on a lower surface thereof. Then, the jig main body 1 a lateral cross-sectional shape, the lateral width L ₂ than the longitudinal width L ₁ at a portion other than the rear end portion
Are widened, and the entire upper surface is an upper water receiving surface 6 and the entire lower surface is a lower water receiving surface 7.

[0019] In this example, the transverse cross-sectional shape of the jig body 1, what is the horizontal width L ₂ than the longitudinal width L ₁ is set to be Hirohaba at portions other than the rear end, which is limited to Instead, the horizontal cross-sectional shape up to the rear end is also represented by the vertical width L _1.
Horizontal width L ₂ may also be a Hirohaba than.

Further, in the upper water receiving surface 6 formed on the entire upper surface of the jig body 1, the area of the water receiving surface 6b on the rear side of the fishing line locking portion 3 is larger than the area of the water receiving surface 6b on the front side of the fishing line locking portion 3. It is larger than the area of the water receiving surface 6a.

Further, in this embodiment, the cross section of the jig body 1 in the lateral direction is a substantially isosceles triangle in which the upper water receiving surface 6 is formed by two slopes (see FIG. 4).

In this embodiment, the upper water receiving surface 6 of the jig main body 1 is formed with a mountain-shaped inclined surface which is inclined forward and backward with the portion where the fishing line engaging portion 3 is provided as a vertex.

The jig body 1 has a front part 8 and a rear part 9.
Heavier than. In this example, the front part 8 is formed of metal and the rear part 9 is formed of resin.

Further, in this embodiment, the position of the jig main body 1 where the fishing line locking portion 3 is provided is changed by the fishing line locking portion 3.
When the jig is suspended, the jig body 1 is set at a position where the jig body 1 assumes a substantially horizontal state (the state shown in FIG. 5).

Next, the operation of the jig of the present embodiment configured as described above will be described. 5 to 9 are explanatory views showing the movement of the jig main body 1 in water.

First, the jig is put into water, and when the jig sinks and the fishing line 2 is stretched, the jig body 1 supported by the fishing line 2
Exhibits a substantially horizontal state in water (FIG. 5).

When the fishing line 2 is pulled upward from this state, the front side rises and tilts due to the difference in the water receiving area (FIG. 6).

When the fishing line 2 is further pulled up, the force applied to the upper water receiving surface 6 by the water pressure acts as a force for pushing the jig main body 1 forward, and the jig main body 1 moves forward while rising (FIG. 7). At this time, the upper water receiving surface 6 of the jig body 1 has a larger area at the rear water receiving surface 6b, but the water pressure from above is applied to the upper water receiving surface 6 of the entire upper surface of the jig body 1; The force in the forward direction that is exerted by the force of the water pressure applied to the water receiving surface 6b is slightly converted into a rotational moment,
At the same time, since the front part 8 of the jig body 1 is heavier than the rear part 9, a weight moment acts on the front part 8 side of the jig body 1 due to the difference in weight between the front part 8 and the rear part 9, thereby causing the forward direction. The jig body 1 efficiently moves forward, and the forward movement over a long distance is obtained.

When the jig body 1 is lifted, in this embodiment, the jig body 1 has an approximately isosceles triangle in which the upper water receiving surface 6 is formed by two slopes. 6 is equally applied to the two slopes forming the upper water receiving surface 6, and the upper water receiving surface 6
Because the two slopes that compose
1) The jig main body 1 can be prevented from skidding when ascending, and can move substantially linearly.

In this embodiment, the upper water receiving surface 6 of the jig main body 1 is formed with a mountain-shaped inclined surface which is inclined forward and backward with the portion where the fishing line engaging portion 3 is provided as a vertex. When the jig body 1 is inclined when the fishing line 2 is pulled upward in the water, the upper water receiving surface 6a on the front side of the fishing line anchoring portion 3 has an angle close to horizontal, while the rear upper surface 6a The water receiving surface 6b is greatly inclined.

As a result, when the fishing line 2 is pulled, the water pressure applied to the rear upper water receiving surface 6b causes the jig main body 1 to move.
The force in the forward direction acts on the front side, and at the same time, the force in the forward direction tends to convert to a rotational moment. However, the hydraulic pressure applied to the front upper water receiving surface 6a is changed by the force in the forward direction to the rotational moment. Therefore, the jig main body 1 moves forward efficiently, and a forward movement of a longer distance can be obtained.

Next, when the fishing line 2 pulled upward is loosened, the jig body 1 released from the upward pulling becomes
The front part is lowered from the weight of the front part, becomes a horizontal state, and moves forward by inertia (FIG. 8).

Thereafter, the front part of the jig body 1 is downwardly directed downward. At this time, water pressure is applied to the lower water receiving surface 7 of the jig body 1 from below, and the force of this water pressure is a force for pushing the jig body 1 forward. Therefore, the jig body 1 moves forward while descending, and a long distance forward movement can be obtained as in the case of the ascent (FIG. 9).

In this way, by repeatedly pulling and loosening the fishing line 2 upward, the jig body 1 is
It moves forward a long distance while ascending and descending, and draws a trajectory as shown in FIG.

FIG. 12 shows another embodiment of the jig according to the present invention. In this embodiment, in the cross-sectional shape of the jig body 1 shown in FIG. 1, not only the upper water receiving surface 6 but also the lower water receiving surface. 7 is also composed of two oblique sides that are approximately isosceles.

By adopting such a configuration, the jig body 1 is equally applied to the two slopes constituting the lower water receiving surface when the jig body 1 is lowered in the same manner as when the jig body 1 is raised, and the jig body 1 is pressed by an equal force. Even when the jig body 1 is lowered, side slippage is prevented, and the jig body 1 can be advanced substantially linearly.

FIGS. 13A, 13B, 13C, and 13D show other examples of the embodiment of the jig head according to the present invention. In the example shown in FIG. The jig body 1 has a horizontal cross-sectional shape in a portion other than the rear end portion, and a fishing line engaging portion is provided on an upper surface side thereof, and a fishing hook is provided on a lower surface side thereof. The width is wider than the width, the entire upper surface is the upper water receiving surface 6, the entire lower surface is the lower water receiving surface 7, and the upper water receiving surface 6 formed by the entire upper surface of the jig main body 1 has: A jig in which the area of the water receiving surface on the rear side of the fishing line locking part 3 is larger than the area of the water receiving surface on the front side of the fishing line locking part 3, and the front part in the longitudinal direction is heavier than the rear part. The jig body 1 has a rectangular cross-sectional shape in the lateral direction.

With such a configuration, when the fishing line is pulled upward in water, the water pressure from above is applied to the upper water receiving surface 6 of the entire upper surface of the jig body 1, so that the forward force exerted by the water pressure is applied to the rotational moment. There is little diversion, a long forward movement is obtained, and when the line is loosened,
Since the front part is heavy, the front part is directed downward and descends. At this time, water pressure from below is applied to the lower water receiving surface 7 of the jig body 1,
The water pressure acts as a force for pushing the jig main body 1 forward, and the jig main body 1 moves forward while descending, so that the forward movement of a long distance can be obtained as in the case of the above-mentioned ascent.

(B) In the example shown in (c), the jig body 1 shown in (a) has an elliptical cross-sectional shape in the lateral direction.

With this configuration, when the fishing line is pulled upward in the water, the force applied to the upper water receiving surface 6 by the water pressure is equally applied to the arcuate surfaces on both sides constituting the upper water receiving surface 6, and the same force is applied to both the arc surfaces on both sides. Since the arc surfaces are pressed against each other, the jig body 1 is prevented from skidding when ascending, and can move forward substantially in a straight line. Also, when the jig body 1 descends, it forms the lower water receiving surface 7 in the same manner as when ascending. The water pressure force is equally applied to the arc surfaces on both sides, and the arc surfaces on both sides are pressed against each other with an equal force. Therefore, even when the jig body 1 is lowered, the jig body 1 is prevented from slipping, and the jig body 1 can move forward substantially linearly. it can.

In the example shown in (d), a ridge 10 extending in the front-rear direction is formed in the center of the upper water receiving surface 6 of the jig body 1 of the jig body 1 shown in (a).

With this configuration, when the jig body 1 is raised,
A ridge 10 formed at the center of the upper water receiving surface 6 of the jig main body 1 prevents the jig main body 1 from skidding, and the jig main body 1 can advance substantially linearly.

[0043]

As described above, according to the jig of the present invention, the vertical movement is efficiently converted into the forward movement,
There is an effect that the fish can be moved forward over a long distance and can be brought closer to the movement of the fish to be simulated. .
